B. Anions have more electrons than protons, giving them a negative charge.
D. Cations have more protons than electrons, giving them a positive charge.
Explanation - Ions are the result of atoms or molecules that lose or gain electrons. If an atom or a molecule is positively charged then it is called as cation and if it has negative charge then it is called as anion.
Cations have positive charge because the atom has lost its electron while anions have negative charge because the atom has gained the electron. The number of protons is more than the electron in cations and less in anions.
Answer:
Mold grows best in warm, humid environments. So, I think B is the correct answer. Answers C and D would actually encourage the growth of mold.
I know that B (Tuberculosis) is spread by bacteria.
Pasteurization is the process where milk is heated up to kill certain pathogens.
Finally, vectors are the agents that carry pathogens from one person to another and spread disease.
Answer:
Predict the possible genotypes and phenotypes percentages for the
offspring produced from the cross below if albinism is recessive in
humans. Albino male x Heterozygous female
aa X Aa = Aa, aa, Aa, aa
Explanation:
From the crossing above, it is right to say that albinism and non-albinism occur in a 50-50 ratio i.e 50% each. The genotype shows that there is 50% homozygous recessive albinism while there is also 50% heterozygous non-albinism. The phenotype reflects that there no dominance of albinism or non-albinism, they both share equal phenotypic characteristics
<span>absorption spectra is your answer. i had the same multiple choice question last year</span>
